"Vaccination with Covaxin produced neutralising titres against all key emerging variants tested, including B.1.617 and B.1.1.7, first identified in India and the UK, respectively," the Hyderabad-based company said.
The company said a modest reduction in neutralisation by a factor of 1.95 was observed against B.1.617 variant compared to vaccine variant D614G. However, despite the reduction, neutralising titre levels with B.1.617 remain above levels expected to be protective, it added.
Besides, no difference was observed in neutralisation between B.1.1.7 and the vaccine strain.
The study was conducted in collaboration with the National Institute of Virology and Indian Council of Medical Research, it said.
